The resolution
The decision establishes three main categories of objects in our solar system.
Planets: The eight worlds starting with Mercury and moving out to Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
Dwarf planets: Pluto and any other round object that "has not cleared the neighborhood around its orbit, and is not a satellite."
Small solar system bodies: All other objects orbiting the sun.
Pluto and its moon Charon, which would both have been planets under the initial definition proposed Aug. 16, now get demoted because they are part of a sea of other objects that occupy the same region of space. Earth and the other eight large planets have, on the other hand, cleared broad swaths of space of any other large objects.
"Pluto is a dwarf planet by the ... definition and is recognized as the prototype of a new category of trans-Neptunian objects," states the approved resolution.
Dwarf planets are not planets under the definition, however.
"There will be hundreds of dwarf planets," Brown predicted. He has already found dozens that fit the category.

Pluto is a planet. It is a dwarf planet. It is just not considered one of the major planets anymore. Pluto is just one of the many ice objects in the outer solar system. It's not even the biggest one. So the astronomers had the choice of making Pluto not a planet or calling all the others planets too. They decided to invent a new category, dwarf planets, and to put them all into it. So Sedna, Xena, Quoar and Pluto are all now called dwarf planets.

because after deliberating on it over a long period of time, the astronomers and people in charge of running the space stations decided after looking at pluto from a distance, it seemed more of a "dwarf planet" rather than a classical planet. the size of pluto looked more like the size of a meteor as well, and the scientists thought that it would be better if pluto was to be considered no longer a classical planet. remember, pluto is still a planet, just a "dwarf planet", but it is no longer listed as one of the nine planets in our solar system.

Pluto is not a planet anymore because it succumbed to a process called definition.

Pluto is no longer a planet not jut because of its size. Also because of its very irregular orbit. When it gets too close too neptune, it gets sucked by Neptune's gravity and revolves around that planet instead.

Scientists were researching pluto when they found a strange thing.Pluto was breaking off the rocks were floating out of pluto.planets dont hv rocks which float away from the planet.They hv rocks which float in the planet.thats the reason

The planet was too far from our solar system.
